Odor trap mechanisms and self cleaning urinal systems

ABSTRACT

Disclosure provides mechanical odor trap mechanism that can be coupled anywhere in the plumbing of a urinal system below the operative base. A receptacle is provided to receive and discharge the fluid from the urinal via a floatation device that is configured to float in the presence of fluid and settle down into the discharge opening in the absence of fluid to sealingly close the opening and block the escape of odor. A self cleaning urinal system can be configured to implement such mechanical odor trap mechanism and further be configured with spraying mechanism disposed at an elevation to spray water and/or air jets to wash away splattered fluid residue. A feces, urine and wash water separating toilet pan can be provided with a lid configured to sealingly close the opening for feces to enable washing without the user shifting positions and also to block odor.

TECHNICAL FIELD

The present disclosure relates generally to the field of odor trap mechanisms and self cleaning urinal systems.

BACKGROUND

Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

Sanitation is one of the most critical aspects that need to be addressed for improving public health. The effects of inadequate sanitation leaves its impact not only on health but indirectly affects a nation's (Gross Domestic Product) GDP as a consequence of treatment cost for diseases, early deaths, lost productivity, and loss in tourist revenue among other factors.

As discussed in patent application 5499/CHE/2014, contamination of water due to improper sanitation, undesirable odor in habitable areas, wastage of water due to indiscriminate flushing are some of the problems associated with urinal systems prevalent today. Several attempts have been made in this domain to improve systems in the art. However, the costs involved in providing desired facilities far outweigh the derived benefits, particularly in economically backward/underdeveloped regions. Also, state of the art odor trap mechanisms are required to be customized for the urinal systems where it is required to be deployed.

Human excreta, particularly urine contain essential plant nutrients which if properly processed can serve as a cost effective source of fertilizer for agricultural production. High content of organic matter in human feces also provides an opportunity for exploitation through composting processes. Composting toilets and toilets with urine separation make it possible to reclaim and utilize human feces facilitating use of the nutrients contained in it as fertilizer and soil conditioner. Ecological sanitation means available are cumbersome to use, necessitating user to move to predefined positions to facilitate separation of feces, urine and wash water for effective recycling of the waste generated.

The present invention in its various embodiments addresses drawbacks and limitations of the systems currently present in the field of odor removal systems and self cleaning urinals.
